Code or rough schematic? I read that when the beam is broken, the voltage goes high, but when the beam is made it pulses for .5ms every 6.5ms. I watched the other video and it didn&rsquo;t look like you had any additional IC&rsquo;s, just the arduino? Thanks for any help / hints!</p>
<p>Thank you for being a great teacher!!!</p>rben13 on Learn.SparkFun.Com and the Arduino Buzzer Beaterrben13urn:uuid:aae33243-b3ac-8fdc-7b3a-8f8958f6b4832012-06-16T05:49:11-06:00<p>This is how education should be, enthusiastic kids devouring knowledge so they can create what they imagine.</p>Vlabs on Learn.SparkFun.Com and the Arduino Buzzer BeaterVlabsurn:uuid:dbf38af8-76b8-916a-4e5c-2cc70e465b432012-06-14T23:07:48-06:00<p>Do you know how happy Riley will be that someone thought he was funny?</p>Vlabs on Learn.SparkFun.Com and the Arduino Buzzer BeaterVlabsurn:uuid:a7d335c3-d673-363d-449b-108470b4253d2012-06-14T23:06:17-06:00<p>They aren&rsquo;t SFE gear, there from the equally impressive electronics shop That is my basement. They are garage door safety sensors. They are 12v but switch to ground.</p>Matt Amacker on Learn.SparkFun.Com and the Arduino Buzzer BeaterMatt Amackerurn:uuid:86990c25-e311-f746-bbd7-19011e3efc852012-06-11T22:06:29-06:00<p>What are those beam-interrupt devices they are using? I&rsquo;m not finding them - they look great!</p>Blacklab1 on Learn.SparkFun.Com and the Arduino Buzzer BeaterBlacklab1urn:uuid:190ad4b0-311c-667a-58be-54f0955dfa452012-06-11T15:24:32-06:00<p>So does this mean that Nate is going to use this to speed up shipping?</p>TheRegnirps on Learn.SparkFun.Com and the Arduino Buzzer BeaterTheRegnirpsurn:uuid:4f54c166-6578-6104-4c5b-de05f9cbe60d2012-06-11T15:01:36-06:00<p>This will be very interesting to follow. I taught AP Physics, Chem, and Math. The vast majority of school systems basically have the funds to buy kits of paper clips and rubber bands and a &ldquo;lesson plan&rdquo;. Can you make a business of this? Many have tried, but few with the variety of resources of Sparkfun. Edmunds comes to mind but they tend to sell one-shot tools and instruments that consume considerable portions of the budget.</p>Ichbinjoe on Learn.SparkFun.Com and the Arduino Buzzer BeaterIchbinjoeurn:uuid:0ba42cb6-4ee9-75c1-17e1-78135f774d872012-06-11T13:08:32-06:00<p>&ldquo;It&rsquo;s the game of the century!&rdquo;</p>
